The Cerro Grande Fire of May 2000 burned almost 43,000 acres of forested land within the Pajarito Plateau watershed in northern New Mexico. Runoff events after the fire were monitored and sampled by Los Alamos National Laboratory. Changes in the composition of runoff water were noted when compared to runoff water composition of the previous 20 years. In order to understand the chemical water quality changes noted in runoff water after the Cerro Grande Fire, a summary of the reported effects of fire on runoff water chemistry and on soils that contribute to runoff water chemistry was compiled. The focus of this report is chemical water quality, so it does not address changes in sediment transport or water quantity associated with fires. Within the general inorganic parameters, increases of dissolved calcium, magnesium, nitrogen, phosphorous, and potassium and pH in runoff water have been observed as a result of fire. However, the dissolved sodium, carbon, and sulfate have been observed to increase and decrease as a result of fire. Metals have been much less studied, but manganese, copper, zinc, and cesium-137 have been observed to increase as a result of fire.
This article discusses how the Department of Energy (DOE) developed the Streamlined Approach for Environmental Restoration (SAFER) to effectively recognize and manage the uncertainties inherent in the environmental restoration process. SAFER integrates the Data Quality Objective (DQO) process with the Observational Approach. DOE and EPA agreed to a joint pilot project test of SAFER. In January 1994, DOE selected four facilities to host the SAFER Pilot Projects: Hanford in Washington, Savannah River Site (SRS) in South Carolina, Oak Ridge National Laboratory (ORNL) in Tennessee, and the Mound Plant in Ohio. The Hanford Pilot focuses on remedial design and remedial action at a reactor area. SRS hosted two pilot projects, both of which were in the remedial investigation (RI) planning stage. The ORNL SAFER pilot project addresses the RI/feasibility study (FS) for a series of surface impoundments. At the Mound Plant, two projects involve removal actions. The third Mound project involves transferring property to the City of Miamisburg. An independent performance measurement team is measuring success in both quantitative and qualitative terms.
